摘　　要：为合理确定临河场地的抗浮设防水位,以弥水春风西地块为例,分析了弥河弥南橡胶坝至三里庄橡胶坝河段的地质环境演变,阐述了弥河与西地块的关系,推求了弥河百年洪水标准的水面线。结果表明:(1)弥南橡胶坝至南环路桥段地质环境演变相对不剧烈,南环路桥至三里庄橡胶坝段演变相对比较剧烈;(2)11+250附近河段与右岸岸坡刚性约束着临弥河侧西地块场地;(3)取路面高程95.20 m作为西地块临弥河侧的抗浮设防水位。研究成果对具有类似地质环境演变的河道的临河场地具有指导意义。In order to determine the ground water level for prevention of up-floating of riverside site correctly,taking the west blocks of“Mishui Spring Wind”Plot as an example,this paper analyzed the geologic environmental evolution of Mihe River reach between Minan rubber dam and Sanlizhuang rubber dam,formulated the relation between Mihe River and the west blocks,and deduced the flood level of one hundred years flood.The result show that:(1)The Mihe River geologic environment between Minan rubber Dam and South Ring Road evolved gradually,and the geological environment between South Ring Road and Sanlizhuang rubber dam evolved dramatically;(2)The west blocks were under the rigid constraint of Mihe River banks of the mileage 11+250 reach and the right bank;(3)Take pavement elevation 95.20 m as the ground water level for prevention of up-floating of the west blocks.The results have important guiding significance for the rivers which have the same geologic environmental evolution.
